Hey, gang! I'm sure many have heard of the FlashQ wireless flash trigger system... If not, it's a new product on the market (as of last month) that is just what the doctor ordered for the Fuji X cameras... In a nutshell, absolutely tiny, radio powered, non-TTL flash triggers.
I just finished testing them extensively with the X-T1 and pretty much anything I could attach to the receiver, including studio strobes (which is what all the product photos were done with), Canon Speedlites and even a Leica SF-24D flash. The system worked every single time and regardless of what was mixed-and-matched, both inside and outside.
I'd be happy to answer any questions about them.
